VALVE-REMOVER.

Specification of Letters Patent.

Patented J une 17, 1919.

T0 all who/a t may concern.'

Be it known that we, Lun A. GALnN'rrNE and HUGH N. GiLLn'r'rn, citizens of the United States of America, residing at Nunda, in the county of Livingston and State of New York, have invented certain new and useful Improvements in Valve- Removers, of which the following is a specification.

The primary object of the invention is the provision of a simple device designed for removing the valves of internal combustion above the valve stem when the device is in use, the invent-ion possessing great strength and being easy and inexpensive to manufacture.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and then claimed.

1n theV drawing forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views,

Figure 1 is a perspective view of the device;

Fig. 2 is a side elevation thereof with the device indicated by dot-ted lines in its open position and with the work also shown by dotted lines;

Figs. 3, 1, 5, 6 and 7 are detail sectional views taken upon lines III-III, IV-IV, VV, VI-VI and VIL-VII, respectively, of Fig. 2.

Referring more in detail to the drawing a Ushaped frame 10 is provided formed `of L- shaped sections 11 and 12, the section 11 being formed of spaced strips 13 between which the section. 12 adjustably resented.

The section 12 is provided with a half turn 14 adjacent its free end forming a terminal foot 15 having a slot 16 in its outer end adapted to receive a valve stem when the device is positioned thereon with the sharpened end portion 17 of the toes at opvposite sides of the slot 16 adapted for fitting beneath the valve spring, as shown by dotted lines in Fig. 2.

The inner end of the section 12 is provided with notches 18 for mounting upon a rivet 19 extending between the resilient side members 13 of the fra-me section 11. A clamping bolt 2O provided with a winged nut 21 connects the side portions 13 together adjacent their free ends for clamping the portions 13 upon the section 12 for retaining the frame sections in their adjusted position. The bolt 2O engages the opposite edge of the frame section 12 from the notched edge thereof which is engaged by the rivet 19 so that the frame is braced against a forcible separation of the forward free ends of the sections 11 and 1.2 and the adjustable connection is made more secure upon tending to separate the free ends of the frame 10.

A spacing plate 22 is provided between the sides 13 of the section 11 spaced from the forward end 23 of said section, while a block 24 is secured between the free ends of the side portions 13 by means of rivets2 and projects outwardly of the free end of the section 11. A plunger 26 is slidably positioned between the plate 22 and block 2li in substantial alinement with the slot 16 when the deviceis assembled, the said plunger' having a pointed inner end 27 adapted for engaging the top of the valve when Vthe foot 15 is positioned beneath the valve spring.

An operating lever 28 having a. handle 29 at its free end is pivoted as at 30 to the outer lend of the plunger 26, while curved parallel links 31 pivotally connect the block 2st with the lever 28 at a point 32 suitably spaced point 27 cent ally above the valve and preferably in engagement therewith. By moving the lever 2S toward the frame section 11, the foot 15 is elevated and the valve spring raised toward the valve. This places the lever 2S into seating position upon the plate 22, it lbeing understood that the entire frame l0 has been elevated by the action ot' the lever 2S, the plunger 2G being held stationary by rea-son of its engagement with the top ot' the valve. The relative positions oi' the pivotal connections of the links 31 and plunger 26 with the lever 2S is such that the force of the spring exerted between the foot l5 and plunger 2G will be incapable oi' returning the lever 28 to its elevated substantially vertical position.

It will be understood that when the device is mounted upon a valve and its stem with the valve spring compressed in the manner described, the Cotter pin or other holding means for the bottom of the spring may be readily removed to permit the removal of the valve stem when the plunger 26 is reshitted or opened for removing the frame 10. The manner of compressing the valve spring by means of our invention will be fully understood as well as the purpose accomplished thereby of permitting the valve stem and valve to be removed from the motor for renewal or shifted in the usual valve grinding operation.

1What we claim as new is l. In combination, an L-sliaped frame section formed of spaced sides, an L-shaped twisted section adapted for positioning therebetween, clamping connections between the said sections, the twisted section having' a terminal foot portion substantially parallel with the free end portion of the iirst named frame section and provided with sharpened toes adapted to tit beneath a valve spring when the device is in use, a reciproeating plunger carried by said free end portion of the frame section having movement toward and away from the said foot, and operating means for the said plunger.

2, A valve remover comprising an L- shaped section having a terminal ioot portion positioned at right angles with the lmain portion of the section and with a slot in its free end forming toes at the opposite sides of the slot, the said toes having beveled ends adapted to engage beneath a valve spring and the inner side of the other end of the section having a plurality of notches, an L-shaped supporting member formed of spaced strips adapted for receiving the notched portion oi' said section adjustably therebetween, a rivet connecting the said supporting portions together adapted for seating in one of the notches of said section, a retaining bolt between the portions of said mounting member adapted for locking said member upon said section when adjusted, and a valve engaging plunger slidably carried by the supporting member opposite the said foot.

3. A valve remover comprising an L- shaped section having a terminal foot portion positioned at right angles with the main portion of the section and with a slot in its ii'ree end forming toes at the opposite sides `of the slot, the said toes having beveled ends adaptedto engage beneath a. valve spring and the inner side of the other end of the section having a plurality of notches, an L- shaped supporting member formed of spaced strips adapted for receiving the notched portion of said section adjustably therebetween, a rivet connecting the said supporting portions together adapted for seating in one of the notches of said section, a retaining bolt between the portions of said mounting member adapted for locking said member upon said section when adjusted, a plate and a terminal block secured between the side portions of said supporting member providing a space therebetween, a plunger slidably mounted in the said space adapted for movement toward and away from the said foot, an operating lever pivoted `to the outer end of said plunger, and curved connecting vlinks pivoted between the said block and lever at a point removed from the point of connection between the lever and plunger.

In testimony whereof we ailix our signatures.
